Katherine's designs reflect great respect for the art and culture of the world. Her rings reflect designs found on tapestry borders, art nouveau illustrations, Japanese prints, and Impressionist paintings. Katherine's line, Studio 311, is carried on today by husband and wife Eric and Krista McCafferty. Today the couple continues to work closely with Katherine in order to preserve the principles that initially guided the creation of the business. Krista collaborates with Katherine to create new designs for the jewelry line, and Eric, who worked as a goldsmith under Katherine in the 1990s, is an integral part of the production aspect of the business.
